Regression Analysis: Price versus Category_2 (Compact), ory_6 (SLR) Analysis of Variance Source DF Adj SS Adj MS F-Value P-Value Regression 5 4793902...

I have such regression model to analyse:

I need to do the following:

A. Write the theoretical regression model describing Price versus Category. Is there evidencethat "Category" is an important predictor of Price? I need to explain my answer.

B. Is there evidence that SLR Cameras are less expensive on the average than SubCompact Cameras? I need to use alpha = .05 and explain answer.

C. I have to construct a 90% Confidence Interval for the average Price of Subcompact cameras and interpret the interval.

D. I need to provide an estimate for the amount on the average that Superzoom Cameras cost.
